由加入美要否簽證

首先，你係攞咩護照先？如果你係攞特區護照就一定要簽証！如果唔係就入唔到境！
以前係可以喺第三個國家辦簽証都得，即係話你喺加拿大玩，然後喺加拿大辦簽証再到美國都可以架，不過呢一、兩年好似比較難搞啦！所以都係喺香港辦定個証，比較好啲啦！

It solely depends on your nationality. Currently, 27 countries participate in the Visa Waiver Program (VWP) (The VWP enables nationals of certain countries to travel to the United States for tourism or business for stays of 90 days or less without obtaining a visa), as shown below:

Participating Countries.
Andorra Iceland Norway
Australia Ireland Portugal
Austria Italy San Marino
Belgium Japan Singapore
Brunei Liechtenstein Slovenia
Denmark Luxembourg Spain
Finland Monaco Sweden
France the Netherlands Switzerland
Germany New Zealand United Kingdom

If you are holding a passport which is issued from one of the above countries, a tourism visa is not required.

任何情形進入美國都要簽證,包括轉機.就算你飛加拿大,飛機先停美國.你都需要簽證.何况而家你要.入境

要先在香港辦妥簽證
